Alberta is seeing the highest daily increases in active COVID-19 cases since April, putting infectious disease experts, doctors and politicians on edge.

Over the past four days, new cases jumped by 509, bringing the province to a total of 1,193 active cases. 

Sixteen regions in the province are also now under a "watch" designation, which means the area has more than 50 active cases per 100,000 residents. The highest is Wheatland County, at a rate of 682.8 per 100,000 people. That's a similar case rate to U.S. states like Missouri, Washington, and Kentucky. 

Craig Jenne, an infectious disease specialist at the University of Calgary, said the weekend's numbers unfortunately confirm that steady increases over the past week aren't a blip. 

And, he said that could mean there's a need to implement more restrictions.

"The more sick people there are, the more infected people there are, the more people that they in turn will infect if we don't bring in additional restrictions. So we need be able to start holding the virus numbers where they are, otherwise we may have to reevaluate some selective closures," he said.

The number of people in hospital has more than doubled over the past week, up to 93, with 16 people in intensive care. 

Calgary continues to be a hotspot, with 589 cases, up from 385 on Friday.

"We've doubled in one week, that's exponential growth. If we double again in one week and again in one week, that means two weeks from now, we will have more active cases in Calgary than we had at the height of the crisis in April. So this is bad. We certainly have more cases now than we did in March when we shut everything down," Calgary Mayor Naheed Nenshi said Monday.

Calgary city council heard presentations from experts on Monday as it weighs whether to make masks mandatory on Calgary Transit. Council is expected to make a decision Tuesday on an amended bylaw which could see masks made mandatory inside all public indoor spaces, with some exceptions. 

Dr. Raj Bhardwaj said if it were up to him, masks would be made compulsory immediately and that rule could be scaled back if the active case rate decreases, rather than waiting for circumstances to worsen before implementing that restriction. 

"This is all about spread within our communities and we're seeing it take off in Calgary ... unfortunately we have to do something about it, the sooner the better," he said. 

Calgary Emergency Management Agency head Tom Sampson said contact tracing has become more difficult, as people who test positive are in contact with significantly more people.

"They're now dealing with 15 to 20 contacts ... they've got a bit of a challenge on their hands," he said. 

Nenshi himself recently had to be tested after a speaker at a city council meeting contracted the illness. The mayor said his test came back negative.
